Northshore Square Mall In Slidell (History And Updates)

Northshore Square Mall Slidell LA

A Once-Dominant Regional Mall Is Now A Redevelopment Story

Northshore Square helped define modern retail in Slidell for decades. The mall opened in 1985 and grew into the Northshore’s main enclosed shopping center, drawing customers from St. Tammany Parish, Washington Parish and nearby Mississippi counties. Morguard’s current leasing materials still describe the site as a 621,292-square-foot regional mall at 150 Northshore Blvd. near Interstate 12, with a broad trade area and high-visibility access along one of Slidell’s busiest commercial corridors.

That role has changed sharply in recent years. The enclosed interior shut down in 2019 after years of tenant losses and changing shopping habits. Since then, Northshore Square has shifted from being a traditional mall story to being a long-running redevelopment story, with recent news focused less on a wave of new inline tenants and more on closures, reuse of anchor buildings, public planning and private investment.

Today, the clearest confirmed activity at the property is concentrated in a handful of large-format spaces. At Home still lists its Slidell store at 150 N. Shore Blvd. Dillard’s continues to operate a Northshore Square Clearance Center. Extra Space Storage also operates at 150 Northshore Blvd., describing its facility as being near At Home at the mall site. Conn’s HomePlus, by contrast, closed during the chain’s 2024 bankruptcy-driven shutdown.

Recent News About The Slidell Mall

The biggest recent developments have involved planning and ownership, not a fully announced roster of new mall stores. In May 2025, St. Tammany Economic Development Corporation board minutes show the organization approved involvement as fiscal agent and project manager for a Colliers development study of Northshore Square, with the study cost listed at $109,000. A January 2025 redevelopment RFP framed the site as an underutilized Slidell property that city leaders wanted to transform into a mixed-use, community-oriented economic driver.

That study turned into a public redevelopment report in January 2026. Colliers said the approximately 54-acre site could support several future concepts, including an event center, distribution or logistics uses, light manufacturing, or a logistics-and-retail hub. The report said the property’s interstate access, nearby hotels and surrounding commercial activity make it a candidate for a different kind of economic use than the enclosed mall model that once thrived there.

In September 2025, Slidell officials briefly moved toward a public acquisition strategy for the property, with council leaders discussing a purchase price of just over $12 million and a possible sales-tax-backed financing plan. One week later, the strategy shifted. The North Shore Square Economic Development District said private-sector interest had prompted officials to step back from a full public acquisition and instead support redevelopment led by private investors.

As for businesses coming and going, the most concrete recent “going” story was Conn’s. In August 2024, the Slidell Conn’s was reported to be liquidating and closing as part of the retailer’s nationwide bankruptcy. The most concrete recent “coming” report is still tentative: in January 2026, Northshore Media reported that a local St. Tammany Parish family had purchased the former Conn’s and JCPenney buildings, and that Adam Acquistapace said his company plans to occupy one of the buildings, though no public opening date was announced.

What Readers Should Watch Next

For longtime Slidell residents, Northshore Square is no longer a simple mall-retail question. The key questions now are whether the remaining retail uses can coexist with a broader redevelopment plan, whether former anchor spaces can be returned to active use quickly, and whether the Northshore Boulevard corridor can attract investment that fits current market demand. The Colliers work suggests the site may be more valuable as a mixed-use economic project than as a traditional enclosed shopping mall revival.

Why This Matters In Slidell

Northshore Square sits near I-12 and one of Slidell’s most important commercial corridors, so any major change there reaches beyond one property line. A successful reuse could affect sales tax collections, jobs, traffic patterns along Northshore Boulevard and nearby hotel and retail activity. A stalled site, on the other hand, leaves a high-profile stretch of Slidell underperforming in a city where newer commercial growth has shifted east toward other shopping areas. That is why recent public discussion has centered on redevelopment strategy, corridor improvement and long-term economic use rather than nostalgia alone.
